Police have been busy advising businesses in Codnor, Heanor and Ripley on how to avoid diesel and fuel thefts.
The visits follow a number of incidents in which businesses in the area were targeted earlier this year, with fuel stolen from vans and lorries parked up overnight.
Officers from the local Safer Neighbourhood policing team have been visiting local firms to offer advice on ways they can improve security and help to deter thieves.
PC Emma Marshall of the Heanor and Loscoe Safer Neighbourhood Policing Team has been making firms aware of the issue and steps they could take.
She said: “We would ask businesses to always be vigilant and to think about ways in which they could potentially help prevent this type of crime and reduce the risk of experiencing the cost and inconvenience of replacing any fuel which is stolen.
“We are committed to working with local communities in any way we can to help keep crime levels low.
“We will always take positive action against offenders.”
Cloudbass, a business which provides outside broadcast facilities, and is based near Codnor, was one of the firms targeted by thieves in February.
Ali Clark, Finance Director for Cloudbass, said: “The biggest impact that the theft had was not just the cost, but mostly the inconvenience for drivers who start their shift early in the morning.
“They cannot set off because they simply don’t have enough fuel and need to refill the tanks before they can get on the road.
“It is good that the police are making businesses aware that diesel and fuel thefts have been happening in the local area.
“We are grateful for the advice they have offered, and have taken steps to increase our security.”
